/** Sound effects such as chorus, distorsions, echo, reverb and similar can
|
||
|
|
be controlled using this. An instance of this interface can be obtained via
|
||
|
|
ISound::getSoundEffectControl(). The sound containing this interface has to be started via
|
||
|
|
ISoundEngine::play2D() or ISoundEngine::play3D() with the flag enableSoundEffects=true,
|
||
|
|
otherwise no acccess to this interface will be available.
|
||
|
|
For the DirectSound driver, these are effects available since DirectSound8. For most
|
||
|
|
effects, sounds should have a sample rate of 44 khz and should be at least
|
||
|
|
150 milli seconds long for optimal quality when using the DirectSound driver.
|
||
|
|
Note that the interface pointer is only valid as long as
|
||
|
|
the ISound pointer is valid. If the ISound pointer gets dropped (IVirtualRefCounted::drop()),
|
||
|
|
the ISoundEffects may not be used any more. */
